2. Big Dipper​The Big Dipper, also known as the Plough or the Saptarishi, is an asterism of seven stars that has been recognized as a distinct grouping in many cultures from time immemorial. The component stars are the seven brightest of the formal constellation Ursa Major. The Dipper is significant because the North Star, the current northern pole star on Earth, can be found using it. Polaris is part of the "Little Dipper", Ursa Minor.Read “Big Dipper” on English WikipediaRead “北斗七星” on Japanese WikipediaRead “Big Dipper” on DBpedia
